5x8 Solid steel rivets with round head DIN 660 50 pcs.

Solid steel rivets DIN 660 — 5 × 8 mm, round head, 50 pieces

Uncoated solid steel rivet with a factory-formed round head and a solid cylindrical shank. The joint is made by riveting the free end of the shank. The size 5 × 8 mm denotes a nominal shank diameter of 5 mm and a length of 8 mm measured under the head. The catalogue specifies DIN 660 and reference PN 82952.

The steel data sheet specifies QSt32-3 or QSt36-3 by agreement. The specific grade has not been confirmed for this offer — it remains to be confirmed. The Rm value and material standard are catalogue requirements in the data sheet; they are not a test result for this batch, a material certificate or a permissible load for the finished joint.

Installation dimensions according to the technical data sheet

Form A denotes a round closing head after riveting; form B denotes a conical closing head after riveting. These are two ways of forming the free end of the rivet. They do not change the factory-formed round head. The s values apply separately to each form, rather than to a common thickness range.

• Installation hole d7: 5,2 mm
• Hole tolerance d7: H12
• Thickness of joined components s — form A: 2 mm
• Thickness of joined components s — form B: 4,5 mm
• Closing head diameter d8: 8,8 mm
• Closing head height k1 — form A: 3 mm
• Closing head height k2 — form B: Approximately 2,4 mm
• Depth t1 — form B: 2,3 mm

Selecting the rivet and riveting method requires consideration of component thickness, hole preparation and the tools used. Tolerance designations are given only where covered by the data sheet; no unconfirmed numerical length deviations have been added.
